LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 503,506, dated August 15, 1893.

Application filed June 16,1893- $erial No. 477,854. (No model.)

To all whom it may concern.-

Be it known that I, OHAELEs E. TRAVES, a citizen of the United States, residing at Los Angeles, county of Los Angeles, State of California, have invented an Improvement in Oilers; and I hereby declare the following to be a full,clear, and exact description of the same.

My invention relates to an oiler which is especially adapted for use upon reciprocating or rotary parts, such as cross-heads, cranks, eccentrics, &c.

It consists in certain details of construction which will be more fully explained by reference to the accompanying drawings, in which Figure 1 is a vertical section through my oiler. Fig. 2 shows its application to a crank pin and its connection.

The object of my invention is to provide a means by which the oil that has passed from the lubricating cup over the bearings, is collected and again returned to the cup without waste.

In the present case I have shown my device applied to a crank pin A with the usual connecting rod B and journal brasses C.

D is the oil cup of any suitable or desired construction which is fixed above the journal or moving part, and it may have any suitable or well known means for regulating the flow of oil. The oil passes down through the bottom of the lubricating cup and through a passage to the part to be lubricated. After having served this purpose, it passes down through an opening G below the journal or moving part, and is collected in a cup H. This cup is provided with a cover I which screws upon it, and between the cover and the rim of the cup is fixed a screen J, which is clamped in place by screwing the cover upon the cup. This screen serves to arrest any impurities in the oil upon its surface, allowing the oil to flow through into the chamber below. The cover has a projecting screw-threaded tubular extension K by which the whole device is easily fitted to the lower part of any connecting rod, eccentric strap, or other moving part, without any extraordinary fitting, it being, only necessary to bore a hole large enough to receive this screw-threaded extension, and the device is thus easily applied to any machinery which is already constructed and in operation.

Below the collecting cup H is a transverse valve chamber L and a hole M is made through the bottom of the cup to allow the oil within the collecting cup to fiow into the valve chamber. \Vithin the chamber L is a valve N of considerable weight and so fitted as to reciprocate freely from end to end of the chamber, a cap 0 screwing upon the end of the chamber serving to retain the valve in place, or to allow of easy access to it and the chamber when desired. When the valve is moved back to the end upon which this cap is fitted, the hole M is opened so that any oil in the chamber H may flow down into the valve chamber in front of the valve. Whenever the valve is moved to the opposite end of the chamber it extends across the hole M, and thus cuts it off altogether, and prevents any entrance of oil while the valve is in this position. The end of the chamber opposite to the cap 0 has an opening which leads into the screw-threaded extension P. By means of a union coupling, the pipe Q is connected with this extension. The pipe Q leads upwardly and discharges into the lubricating cup D upon the top of the journal.

Within the extensionPis achamber which contains a check valve R, and this check valve is normally closed against the inner end of its chamber by the weight of oil in the pipe Q above it.

The operation of the apparatus will then be as follows: When in motion, the reciproeating, rotary, or other similar motion of the part which carries the lubricator and my collecting and pumping device, causes the valve N to reciprocate within this chamber, first moving to the end upon which the cap is fitted, which allows the oil in the chamberHto flow down into the valve chamber in front of the valve; a reciprocation or movement in the opposite direction causes the valve to move by its inertia so that it first closes the opening M by passing across it, and then it acts as a piston, and its weight and momentum are sufficient to force any oil which is between it and the open end of the valve chamber through this opening, the check valve being moved to allow the oil to pass into the pipe il The valve is 0i considerable weight S0 that its motions are positive and of suit for cleaning purposes, and the movement of t]: le oil is elfected by a. positive reciprocating plston \vhich combines in itself the two func-c' Lions of piston and valve.

Havin thus descrbed Iny invention, what I claim as new, and ters Patent, is

3. In an eiler, the colnbination with arfeed cup located above the part to be lubricated and connected therewith by a supply passage,

of a delivery passage leading from the lower part of the journal, a collecting cup fitted to the lower end of the discharge passage, a transverse chamber situated below the cup, and a passage leading from the cup into this chamber, a reciprocating piston movable within the chamber, and adapted to open and close the opening between the cup and the chamber during its reciprocations, a discharge passage from thc end of the chamber, and a pipe connecting said passage with the feed cup above and a check valve fitted in the discharge passage, substantially as' herein described. T i V 2. A collecting device and returning pump for lubricatcrs consisting of a cup removably attached to the lower part of the journal having a passage connecting therewith whereby surplus oil passes into the cup, a transvcrsc chamber situated below the cup having a pasesire to secure by Letare lhnughvhich oil from the cup nayilow into the chamber, a reciprocating piston movable 1n the chamber by the l nertla caused by the movements of the journal or part to be lubricated, ar removable cap at one end of the chamber, a. discharge passage and check valve at the opposite end of the chamber and a. pipe connecting this passage with a. feed cup above the journal or part to be lubricated. whereby a constant circulation of lubricating material is effiected, substantially as herein described,

3. An oil collecting and returning pumping attachment for crank in ournals and similar movable parts, consisting of a cu having between the cover and the cup, a. screw-threaded extension from the top of the cover by aremovable screw cover and. a. screen secured valve in the discharge passage to prevent the 7 CHARLES E.
